Answer
Explanation:
Step1: Calculate amount in each bank
The amount deposited in First Oak and West United is $\frac{1600}{2}=800$.
Step2: Calculate simple - interest from First Oak
The simple - interest formula is $I = Prt$, where $P$ is the principal amount, $r$ is the annual interest rate, and $t$ is the time in years. For First Oak, $P = 800$, $r=0.06$, and $t = 5$. So $I_1=800\times0.06\times5=240$.
Step3: Calculate compound - interest from West United
The compound - interest formula is $A=P(1 + r)^t$, where $A$ is the amount of money accumulated after $n$ years, including interest, $P$ is the principal amount, $r$ is the annual interest rate, and $t$ is the number of years. For West United, $P = 800$, $r = 0.05$, and $t=5$. So $A=800\times(1 + 0.05)^5=800\times1.05^5=800\times1.27628=1021.024$. The compound interest $I_2=A - P=1021.024−800 = 221.024$.
Step4: Calculate total interest
The total interest $I=I_1 + I_2=240+221.024 = 461.024\approx461.02$.
Answer:
$461.02$
